Applied immutablity to classes where applicable, and vigorously unimport Moose keywords when they are no longer needed. This results in x 2 performance as far as defining a Bread::Board model (Daisuke Maki).
Bread::Board
Implemented unimport(), thus allowing you to remove keywords exported by Bread::Board (Daisuke Maki).
Bread::Board::Traversable
Unrolled recursive calls to loops, and removed Sub::Current dependency (Daisuke Maki)
